pow4
A shortcut to calculate the fourth power of a value (x^4), used for creating visual effects with extremely high contrast and very exaggerated easing curves.
Core Advantages
Applies a much steeper quartic curve than cubic, rapidly 'crushing' smooth gradients or inputs into a near black-and-white, hard-edged result, ideal for creating dramatic high-contrast visuals.
Common Uses
Creating extremely sharp specular highlights
Implementing exaggerated 'Ease-In' animations
Generating hard-edged masks from grayscale images
How to adjust
This node has no adjustable parameters; it always applies an extremely strong quartic transformation. Compared to `pow2` or `pow3`, `pow4` pushes mid-range values towards 0 much more aggressively, preserving only the values closest to 1, thus producing the strongest contrast effect.
Code Examples
1// Apply pow4 to dramatically increase contrast,
2// crushing a soft gradient into a hard edge
3const sharpCircle = pow4( softCircle );
